Content-Type: text/plain Message-Id: <20161104113250.664F7E0BC8@git1-us-west.apache.org> Date: Fri, 4 Nov 2016 11:32:50 +0000 (UTC) archived-at: Fri, 04 Nov 2016 11:33:17 -0000 Github user tillrohrmann commented on the issue: https://github.com/apache/flink/pull/2629 No this case can also happen if you don't have an input for a really long time, e.g. a completely consumed Kafka topic to which no data is written anymore. In this case you would still like to output the pending elements asap without adding the latency of waiting for a new element to arrive. --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well. If your project does not have this feature enabled and wishes so, or if the feature is enabled but not working, please contact infrastructure at infrastructure@apache.org or file a JIRA ticket with INFRA. ---
